Standard Specification for Large Diameter Polybutylene Plastic Pipe (Withdrawn 2006)
1.1 This specification covers polybutylene (PB) pipe made in dimensions based on outside diameters from 3.5 to 42 in. in six standard dimension ratios, namely 11, 13.5, 17, 21, 26, and 32.5.
1.2 The outside diameter sizing system is known as the IPS system, whose measurements are in inch-pound units.
1.3 The piping is intended for new construction and insertion renewal of old piping systems used for the transport of water, municipal sewage, industrial process liquids, effluents, slurries, etc. in both pressure and nonpressure systems. The components covered by this specification are intended for use in commercial and industrial process piping at temperatures up to 180°F.
1.4 All pipes produced under this specification are pressure-rated.
1.5 This specification includes criteria for classifying PB plastic pipe material and pipe, together with performance requirements and test methods for determining conformance to the requirements.
1.5.1 Quality control measures to be taken by manufacturers are outlined in the Appendix as a nonmandatory part of this specification.
